Magento advises the utilization of specific cache technologies to enhance the efficiency of your store. When selecting a hosting provider for your Magento store, ensure that these caches are enabled on the Magento server.

• Varnish Cache: Functioning as an HTTP accelerator, Varnish is designed to boost the performance of content-heavy web applications like Magento.

• Memcached: Memcached serves as an open-source distributed memory caching system, alleviating load by storing data objects in dynamic memory, serving as short-term memory for web applications.

• Redis Cache: Redis, an open-source (BSD licensed) solution, serves multiple purposes as a database, cache, and message broker. It offers diverse data structures, including strings, hashes, lists, sets, sorted sets, bitmaps, hyperlogs, geospatial indexes, and streams.

• PHP OPCache: Magento officially recommends PHP OPCache, which compiles and caches PHP scripts into bytecode instead of compiling them with each request. This approach significantly enhances the overall performance of the application.
